This invention relatesto a machine which has been more particularlydesigned for staining bundles of shingles.

One of its objects is the provision of a machine of this character whichis simple, compact and rugged in construction, which is reliable andefiicient in operation, and which is not liable'to get out of order.

Another object of the invention is to provide a power-driven machine ofthis character having means for lowering and raising the bundles ofshingles into and out of the stain-tank and for automatically arrestingthe movement of the bundles when they reach the end of theirpredetermined travel in either direction.

in the accompanying drawings I Figure 1 is a front view of the machineembodying my invention. Figure 2 is a side View thereof. Figs. 3 and 4are fragmentary rear views thereof showing the position of the partsduring the lowering and raising movements of the shingle-carrier orbasket, respectively. Figure 5 is a fragmentary rear view of thebelt-shifter bar and its operating lever, the parts being shown in theirnormal or neutral position. Figure 6 is a fragmentary sectional sideview of the trip device for automatically controlling the downwardmovement of the shingle-carrier. Figure 7 is a side view of modifiedform of the in vention. Figure 8 is a rear view thereof.

Similar characters of reference indicate corresponding parts throughoutthe several views.

in its general organization, this improved machine comprises a tankcontaining a quantity of stain into which the bundles of shingles aredipped, a carrier or basket for the shingle-bundles suspended formovement relative to the tank, means for lowering and raising thecarrier into and out of the tank, and means for automatically arrestingthe movement of said carrier when it reaches the end of itspredetermined travel in either direction.

Referring now to the embodiment of the invention illustrated in Figs.15, inclusive, 10 indicates the tank for the stain which rests on thefloor and which may be rectangular or any other desired shape. This tankis open 2 I 14 from any source of power.

Rising from the opposite side walls ofthe tank are columns or channelbeams 15 on which the shingle-carrier or basket 16 is guided forvertical movement into and out of the tank. This carrier preferablyconsists of sheet metalside walls 17, and a forwardly inclined bottommade up of a series of rollers 18 journaled at their ends in said sidewalls. Below its upper end the carrier has a plurality of transversebars 19 between which and the rollers 18 the bundles of shingles areplaced, the bars serving to hold the latter down into thestain when thecarrier is submerged therein. Atits rear or discharge end the carrierhas a downwardly swinging door 20 which is normally held in its closedposition by springclamps 21 or other equivalent means. During thedipping operation, this door is closed to prevent the shingle-bundlesfrom falling out of the carrier, while in its open position, shown inFig. 2, the same serves as a platform for supporting the bundles duringtheir discharge fromthedipping machine. front or feed end and thebundles of shingles are placed side by side in an uprightposition, asshown by dotted lines in Fig. 1.

The carrier is guided for vertical'move-,

ment on the columns 15 and for this purpose has guide rollers 22engaging the channels of said columns, these rollers being mounted onthe ends of a shaft 23 secured to the carrier. Near its upper end, thecarrier has a suspension bar or member 24 which passes throughlongitudinal slots 25 in the columns and whose outer ends are connectedto an elevating mechanism which will presently be described. Theengagement of the suspension bar with the column-slots prevents lat- Thecarrier may be openv at its eral swaying of the carrier during itsraising v and lowering movements.

The elevating mechanism for the carrier 16 preferably consists of a pairof endless chains 26 which pass at their lower ends .of two notchesaround corresponding sprocket wheels 27 loosely mounted on the agitatorshaft 12 while their upper ends pass around sprocket wheels 28 fixed onthe ends of a driven shaft 29 j ournaled in bearings 30 attached to thecolumns 15. Each chain is connected by a bolt or otherfastener 31 to thecorresponding ends of the suspension bar 24, so that as the chains aredriven in one direction or the other, the shingle-carrier is accordinglymoved to bring it into or out of the stain-tank l0. Counterweights 32applied to each chain serve to hold the carrier in its elevatedposition. Mounted on the driven shaft 29 are loose pulleys 33, 34 and atight pulley 35, the pulley 33 being connected by a straight belt 36with the corresponding pulley fixed on a driving shaft 37 and thecompanion pulley 34 being connected by a crossed belt 38 with a similar,pulley on said driving shaft. Thus, when the belt 36 is shifted on tothe tight pulley 35, the shaft 29 is driven in a clockwise direction tolower the carrier into the tank, and when the belt 38 is shifted ontothe tight pulley, said shaft is driven in a counter-clockwise directionto elevate the carrier. These belts are shifted into and out ofoperative engagement with the tight pulley by a laterally-shiftable bar39 guided near'its ends in brackets 40 secured to the columns 15 andcarrying coupling yokes 41 embracing the corresponding belts 36, 38.This belt-actuating bar is shifted in one direction or the other by anoperating lever 42 fulcrumed at 43 to an arm 44 attached to the adjacentcolumn 15. Normally, this operating lever is held in a substantiallyvertical neutral position, shown by full lines in Figs. 1 and 5 and bydotted lines in Figs. 3 and 4, by a vertically-swinging locking pawl 45engaging a notch 46 in the belt-shifter bar and held therein by a spring47. A trip arm 48 connected by a link 49 with a supplementary actuatinglever 50 located adjacent the handle of the operating lever 42 serves toeffect the release of the locking pawl from the bar 39 to permitshifting the latter in either direction when desired. A coil spring 51attached at one end to one of the columns 15 and at its other end to thebelt-shifter bar acts to constantly urge the latter to its neutralposition.

Means are. provided for automatically arresting the movement of theshingle-carrier 16 when it reaches the end of its predetermined travelin either direction, this mechanism operating in conjunction with thebeltshifting bar 39 and its associated parts. To this end, the mechanismfor arresting the downward movement of the carrier consists of avertically-movable plunger or locking bolt 52 located at one side of themachine and guided in brackets 53, its upper end having a tooth 54arranged to interlock with either 56 located in the lower edge of thebar 39 and its lower end having a coil spring 57 applied thereto andinterposed between the adjacent guide bracket and a collar 58 fixed tothe plunger for constantly urging the same upwardly into engagement withsaid bar. The lower end of the plunger is bent laterally to form atappet arm 59 with which a trip lug 60 fixed on the side wall of thecarrier is adapted to engage as the latter approaches the end of itslowering move ment, as shown in Fig. 6. When the operating lever 42 isshifted from the dotted line to the full line position shown in Fig. 3,the belt 36 is shifted on to the drive pulley 35 to turn the chains 26in the proper direction to lower the basket. In shifting the bar 39 tothe position shown, it is held in suchposit-ion by the plunger-tooth 54interlocking with the notch thereof. As the carrier reaches its immersedposition in the tank, its trip lug engages the tapbet arm of the plungerpulls the latter downwardly with it, thereby releasing the locking toothfrom the beltshifter bar and permitting the spring 51 to return it andthe operating lever to neutral position. For the purpose of positivelyholding the carrier down in the tank, while the shingles are beingcovered with. the stain, catches 61 may be applied to the suspension bar24 for engagement with the flanged upper edge of the tank 10 or otherfixed part of the machine, as seen by dotted lines in Fig. 3.

In lifting the carrier from the tank, the operating lever is shifted tothe position 'shown by full lines in Fig. 4, in which position thecrossed belt 38 is engaged with the tight pulley 35. The automatic meansfor arresting the upward movement of the carrier and shifting thecontrolling elements to their neutral position consists of an arm 62rising from the carrier 16 and terminatin its upper end in a cam face 63which is adapted tocontact with a roller 64 on the belt-shifter bar 39as the carrier approaches its elevated position. Said bar and itsoperating lever 42 are held in the position shown by full lines in Fig.4 by the plunger-tooth 54 engagin the notch56 in the bar. When the cam63 engages the roller 64, it automatically shifts the bar 39 andoperating lever to the dotted line position shown in Fig. 4, it beingunderstood that the parts are normally retained in such position by thepawl 45 interlocking with the notch 46 in said bar.

Briefly stated, the operation of the machine is as follows Assume theparts to be in the position shown in Figs. 1 and 2, with the swingingdoor in its raised or closed position. After loading the carrier 16 withthe bundles of shingles, the same is lowered into the staintank 10 byshifting the operating lever 42 from the dotted line position to thefull line position shown in Fig. 3. When it is fully immersed in thetank, the carrier is automatieally stopped and the operating lever isreturned to its neutral position in the manner heretofore described. Thecarrier is allowed to remain in the tank for about two minutes, duringwhich time the shingles are thoroughly coated with the stain. Theinclined disposition of the shingle-bundles in the carrier not onlypermits the ready displacement of air between the shingles of a bundlebut it also results in a rapid and uniform distribution of the stainover the shingles. 'Afterthe shingles have been immersed for therequired period of time, the carrier is lifted from the tank by firstreleasing the catches 61 and then shifting the operating lever tothefull line position'shown in Fig. 4. Upon reaching its elevatedposition shown in Figs. 1 and 2, the carrier is automatically"arrestedin the manner previously described, the door 20 is dropped and thebundles of stained shingles are discharged from the carrier, after whichthe latter is ready to receive another supply of shingles. The inclinedroller bottom of the carrier materially facilitates the discharging ofthe shingle-bundles, it being only necessary to give them a slight pushto effect their removal.

In the modified form of the invention shown in Figs. 7 and 8, thecarrier 65 is raised and lowered through the medium of suspensionelements in the form of fixed nuts 66 applied to its side walls andengaging upright screws 67 driven from a driving shaft 68 byintermeshing bevel gears 69. This shaft is driven in one direction orthe other by belts and pulleys in the manner set forth in the firstdescribed construction. The belt-shifting bar is indicated at 70 and itsoperating lever at 71, the latter having a locking latch 7 2 controlledby a supplementary hand lever 7 3 for holding it in neutral position.This embodiment of the invention also has a plunger or looking bolt 74arranged to interlock with the belt-shifter bar when the parts are inthe position shown by dotted lines in Fig. 8, and is adapted to beautomatically released therefrom when the carrier reaches the end of itsdownward movement by a trip arm 7 5 arranged in the path of a collar 76on said plunger. 7

For the purpose of heating the stain in the tank and permit its moreready penetration into the shingles, a steam pipe 77 or similar heatingelement may be applied to one of the inside walls of the tank, as shownin Fig. 1.
